of shoes, and that will be adjustable to different sizes of heels.

According to present practlce, the heel is cut out by hand, the method being to first attach the forwardpart of the sole to the shoe, and then cut away a marginal portion of the rear unattached sole. This constitutes a comparatively slow process, as all hand work is compared to machine operations. An effort to speed up production often results in inaccurate work. My invention, being essentially in the nature of a machine or tool, aims to eliminate the uncertain element inherently connected with hand work, to produce more uniformly accurate work, and to give greater production.

In the accompanying drawings Fig. 1 is a plan view embodying my intention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a plan View of a modification of my invention, without the gage.

Fig. 4 is a plan view of the cut made by the die of Fig. 1.

Referring to the drawings, 1 is the body of the die, attached to which is the U-shaped cutting lade 2 and the blades 3 and 4. The gauge 5 consists of an element 6 containing a slot 7 therein, extending longitudinally in the direction of the sole. Positioned within this slot is the pointer 8, which is free to move therein. The calibrated index 9 serves to determine the position of the pointer 8 to correspond with various sizes of shoes.

hen applying the die to an unattached sole, it will cut out a marginal border 10 at the rear of the sole 11, and will also form the slits 12 and 13, producing flaps 14 and 15. After the sole is applied to the shoe for heeling, these flaps allow a forward and backward adjustment of the heel, so as to render the cut-adaptable to heeels of dif ferent lengths. lVhen the position of the heel is once determined, the flaps are cut off at the junction of the heel and the upper of the shoe.

To render the die more accurately adjustable to different sizes ofheels, the gauge 5 is employed. The calibrations on the in den 9 are previously determined by experiment for different lengths or sizes of heels. In the process of operating this die, the pointer 8 is set to the desired reading preliminary to applying the pressure for cutting. For a short heel the pointer 8 is placed close to the rear of the blade 2, and for longer heels it is removed farther away from the blade. The point 16 of the pointer is then placed at the rear end 17 of the sole, the die positioned over the heel seat area 18 of the sole, and the pressure ap plied for cutting. It will thus be seen that the longer the heel, the more forward is the positioning of the die on the sole, and the nearer the slits 12 and 13 to the front of the sole.

The die 19 with blade 20 is a simplified modification of my invention, and is particularly applicable to the process of cutting out the heel seat after the sole is attached to the shoe.

\Vhile I have herein shown two embodiments of my invention, it is manifest that many changes may be made in the configuration of the die, within the scope of the appended claims.

lVhat I claim is 1. A die of the class described containing a body portion and a cutting edge comprising a U-shaped blade with two blades situated one on each side thereof, the said two blades being transverse to and at an angle to the sides of the U.-shaped blade and extending outwardly therefrom and positioned away from the extremities of the two sides of the saidU-shaped blade, said U-shaped and transversely positioned blades being arranged to remove a marginal bor-- der at the rear of the sole and to form forwardly extending slits adjacent to the front part of the heel seat.

2. A die of the class described comprising a body portion,a cutting edge, and a gauge for adjusting the die for various sizes of heels, the said cutting edge consisting of, a U-shaped blade with two blades able in the longitudinal direction of the situated one on each side thereof, the said sole, and a calibrated index arranged to de- 10 tWo blades being transverse to and at an termine the position of the said pointer angle to the sides of the U-shaped blade with relation to the said U-shaped blade for and extending outwardly therefrom and {10- various sizes of heels.

sitioned away from the extremities of the In testimony WhereofI hereby affix my sides of the U-shaped blade, the said gauge signature.
